Your research into a nation has yielded the following information: Autonomous expenditure (A) = $3,000 Gross investment (I) = $2,000 Government purchases (G) = $2,500 Net exports (NX) = –$1,000 Taxes (T) = $2,000 MPC = 0.75 Instructions: Round your answers to nearest whole number. For the coefficient to Y, round your answer to 2 decimal places. a. Substitute the values above into the equation: AE = A + [MPC × (Y – T)] + I + G + NX to determine the abbreviated equation for aggregate expenditures (AE).

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
